To all whom t may concern:

Be it known that I, EDWIN B. STRANGE, a resident of New York city, borough of the Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Pails, of which the follow- `ing is a specification.

One of the objects of my invention is to provide a pail of integral fibrous pulp material which shall be cheap to manufacture,

strong and durable and not liable to be tion is to provide a pulp structure having a plurality of sections and ribs so arranged relative to each other that the pressing and forming of the same will result in a more strongly braced and reinforced structure; and further to provide a cover so arranged as to prevent crushing when the lled pails are stacked one upon the other, and means for securing the cover in position on the ail. -p My `invention further comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a perspective view of a pail embodying my improvements;

Fig. 2 is a cross section on the line 2, 2, in Fig. 1;

Fig. 8 is an enlarged detail section on the line 3, 3, in Fig. 1; 1 Fig. 4 is a corresponding view at the op'- posite side of the pail; and

Fig. 5 is a detail hereinafter referred to.

The pail 1 has sides -or walls 2 anda bottom 3 made integral, comprising fibrous pulp in suitable compressed form, which may be compressed to shape in any well known manner. At the' inner corner 4, where the sides and bottom join, thematerial is increased in thickness and made in a concave form in a continuous manner, in-

.tegral with the sides and bottom, serving to increase the strength at the junction between the sides and bottom of the pail, to

prevent the bottom and sides from becoming Speoilcation of Letters Patent.

cracked or broken during use, which is liable to occur where pails of this character are made with sharp or substantially right langled corners at the junction of the sides j with the bottom. This manner of constructing my improved pail may be carried out by sultably shaping the plunger at its outer edge, in rounded or convex form,fso that the material of the pail when the same is pressed or squeezed will provide a filling at the corner between the sides and bottom, thereby lncreasing the dimension of the material from such corner to the pail. ,The bottom of the pail is shown recessed at 6 providing an annular rim 7, whereby the bottom of the pail may be made of the required thinness and yet strength is alorded-at the margins by the rim 7 in conjunction with the filling 4.

The pail is formed of homogeneous pulp outer edge 5 of the material by pressing wet pulp in such a wayA as to form integral sections and ribs that are so arranged relative to eachother by the pressing and forming of the structure that the pail is braced and reinforced throughout and greatly strengthened thereby.

y forming a pair of ribs 8 substantially parallell with each other and the adjacent ribs diverging therefrom from the bottom upwardly as clearly shown in Fig. 1, the narrower sections 9 are substantially rectangular and the wider sections adjacent thereto on either side throughout the circumference of the structure gradually widen from the bottom to the top of the pail, thereby providing a wedging and reinforcing action both during compression and after the pulp has hardened that increases the density of the pulpand supplements the action of the ribs, some of which substantially parallel each other, while others diverge from the parallel ribs in such manner as to brace the homogeneous integral brous pulp pail in all directions and greatly strengthen it and hence make it commercially practicable for carrying heavy substances of various kinds.` v

The sections 9 and 10, the ribs 8, the bottom 3, and the enlarged reinforcing corners 4 on rthe inner side of the pail are all pressed integrally by means of a suitable press from homogeneous fibrous material, and after the pail has been thus formed it is dried and allowed to set and harden, as a result of which a light inexpensive and substantial pail is formed, which has no joints or seams to afford leakage, joints or corners to house and carried upwardly, and its two parts are or collect foreign material, or regions of secured together, as by crimping them by a weakness to permit rupture of the pail. suitable tool, as shown at 21.
